QUESTION
I am running a B2B website, where customers login, view the catalog and place orders. The website runs on a sub-domain (I think this is an important side note because of this). By the time customers finish their order and click on the place order button, they are sent back to the login screen, loosing their order. Sometimes, this period is shorter sometimes longer. Something to do with the Application Pool being restarted?.
So I created a logging functionality to see what's happening and came to find out whenever a user logs in, the following logs are created:

Answered 2021-Apr-10 at 14:13If you are unable to use any of the default key persistence methods, there are other options available, e.g. storing the key in a Database (via Entity Framework), Redis, Services like Azure KeyVault etc.
See Key Storage Providers for more details.
QUESTION
I am kind of new to SQL and web-programming right now, so I am doing a little project for myself to get to know every aspect of developing a website (yup, from frontend to backend and sql).
So the point is that potentially I may have a lot of data in my table, like over 3k rows [elements] (relatively a lot) with a bunch of columns [properties] as well. And I know from the beginning that it could be split on, say, four tables. For example, by color. Each element of each color has the same amount of keys and keys itself
So the question is how I could estimate the ratio of time:memory efficiency in this case. I do understand that it is much quicker to search for information in a smaller table, but I have no idea how do SQL tables are stored. For instance, how much additional memory each table costs without.
...ANSWER
Answered 2021-Feb-08 at 17:543,000 rows is small for SQL. You don't want to split large tables, because SQL has strong capabilities for handling larger data. Three come to mind:
- Sophisticated query optimizers.
- Indexes.
- Table partitions.
In addition, the way that data is stored incurs overhead for small tables -- not large ones. Rows are stored on data pages. And data pages are typically measured in thousands of bytes. So, a small row with 100 bytes still occupies one data page -- even if the page could store one hundred such records. And the overhead for reading the data page is the same.
In summary. Your table isn't big. And SQL is optimized for larger tables. So, no need to change your data model.
QUESTION
I'm simply trying to use Serverless and Lambda to make get and post requests to my Atlas cluster. I've followed all the tutorials below which are very similar:
https://hackernoon.com/building-a-serverless-rest-api-with-node-js-and-mongodb-2e0ed0638f47
https://dev.to/adnanrahic/a-crash-course-on-serverless-apis-with-express-and-mongodb-193k
https://dev.to/saigowthamr/build-and-deploy-a-rest-api--using-serverless-express-and-nodejs-3331
Using Insomnia or Postman I can make get and post requests to a locally hosted database but not to an Atlas cluster. The requests always result in 502 Bad Gateway with JSON message of "internal server error". I've tried switch up the cluster host from AWS to Azure and that didn't help. In regard to the various drivers I've tried every variety of connection string. I've whitelisted all ips so access is not an issue. Please help.
...ANSWER
Answered 2019-Nov-18 at 16:35I the deleted the cluster, project, organization, and users in my Atlas account and started over. I didn't manually create a new user through the Network Access tab but rather created a user with the prompt you get when creating a Cluster. I noticed there was a note regarding special characters when making a connection:
When entering your password, make sure that any special characters are URL encoded.
My previous password used an @ symbol which may have been causing problems. So be careful when using email addresses as user names. I assigned 0.0.0.0/0 to the user as usual. I don't think it matters but I only have one user and I added a comment to that user as well. Now I can make a connection using the 2.2.12 or later Node.js driver connection string. I hope this helps someone.

QUESTION
I'm trying to make a real estate agency website and got an idea of saving addresses as coordinates to database (because text addresses can be difficult)
So I have two main questions:
1) Is it possible to search objects by street if their addresses are saved as coordinates? And how difficult is it? Maybe you could give a working example in any web-programming language or advise a good walkthrough.
2) Is it a feasible approach? Maybe it has awful drawbacks I don't see.
...ANSWER
Answered 2018-Mar-14 at 15:39Yes, it is in fact possible to convert the latitude and longitude of a location into an address. This is achieved through the Google Maps Reverse Geocoding service through the Javascript API.
Here is a code sample of a reverse geocoding request: Live example here

A newbie in ASP.net core. In fact, a newbie in ASP.net/ web-programming. I have encountered an error message "Format of the initialization string does not conform to specification starting at index 77" when trying to create EF model based on my existing database in ASP.net core 2.0. Help is much appreciated. Thanks in advance.

Answered 2018-Sep-24 at 10:39I think your connection string looks a bit odd, I'm not sure that colon should be there? Password=SecretPass, that's my guess.
QUESTION
my question is really simple, but I cant figured it out, because I'm not so good with web-programming.
Is it possibile to have a MultiLanguage label/ input value for a .html page ?
I need to show some text if the default browser Language is Italian, and another text if the browser is with another Language. For Example I need to automatically switch from Ciao to Hello.
Is there a way to achieve that ? Maybe I can do that with Javascript...
Thanks all.
...ANSWER
Answered 2017-Jun-15 at 15:11There are many, many different ways to go about this, and I advise you to put some time into searching google and finding the way that best suits your needs.
I will give you an example I like to use, but keep in mind that the information I'm posting is only one out of a multiple possible approaches.
First off, you have to get the user's language. To do this you can either use geolocation and base the language off of where the user is (see this answer for a good way, or search google and use one of many other approaches), or you can get it from the user's browser (see this thread for information on doing that).
Once you have that, it's just a matter of displaying localized content to the user. My preferred approach is the following, which combines all variants into a single file (alternative ways of doing this utilize multiple different HTML files):
First off you have your HTML:

So, in web-programming class (a few weeks ago) we started a project to make our own website. Now, most things are going fine, though I tried to center my page it didnt work. I don't know why it doesn't work either, I'm thinking it might be something in the codes that might block/counter it, but I don't know. I basically want the whole html centered. I used an ID which I named "wrap" on the div tag after the bgcolor tag as you will see.
